INSTALLATION
Please read and follow the installation instructions carefully to avoid injury or damage to the
compressor and your vehicle.
Each of our air compressors and parts have been carefully produced and packaged. Before you
begin installation, please familiarize yourself with Installation Parts List (Fig. 1) of this manual. Guidelines for Selecting Mounting Location:
The selection of proper mounting location for your air compressor will help ensure a long and trouble
free compressor service life. Please pay close attention to the following guidelines:
1.Select a FLAT, UPRIGHT AND SECURE location where the compressor can be mounted.
2.To maximize air compressor performance, locate compressor as CLOSE TO THE BATTERY as
possible so that length of positive lead wire required is at a minimum. 3.Choose mounting location that is as cool as possible and AWAY FROM HEAT SOURCES.
The cooler the ambient temperature, the less chance the compressor will overheat.
4. This compressor is moisture & dust resistant, but NOT DIRT OR WATERPROOF. Do not mount
compressor in locations where the unit is likely to come in contact with the elements.
5.For compressor with remote filter mounting, select compressor’s mounting location where air line
can be routed from compressor air inlet to remote inlet air filter. Make sure that the remote inlet air
filter is located in a dry location, away from the elements. 6.You will also want to select a compressor mounting location where the leader hose bracket can be
mounted to leader hose. (Not applicable to P/N 32534)
7.If it is necessary to mount the air compressor further away from the battery, such as inside
your vehicle or in the bed of your pickup, use a positive lead wire for remote installation. Refer to the wire gauge guide on the back of this manual.
8.Do not mount compressor near areas where flammable liquids are stored.
9.Use thread sealant for proper fitting installation. Teflon tape is not recommended.
Properly sealed, recommended torque is 12 to 15 ft. lbs

MOUNTING AND WIRING
1. Disconnect ground cable from vehicle’s battery.
2. Temporarily position the air compressor in the location where it will be mounted.
3. Route ground wire to the negative post of the battery or to an appropriate grounding point and
cut ground wire to length as needed.
4. Mount air compressor with the four sets of bolts, nuts, washers, and locking washers provided. (See Fig. 2 for Mounting Instructions) Use of thread sealant recommended.
5. NOTE: For remote inlet air filter installation, refer to instructions included in the Remote Inlet Air Filter Pack.
6. This air compressor may be equipped with a heavy duty heat resistant leader hose. This leader
hose is designed to prolong the life of your air line. Do not remove this leader hose from air
compressor. (Not applicable to P/N 32534)
7. IMPORTANT: Please note, the leader hose that may be equipped with your compressor may
also have a built-in inline check valve. Do not remove inline check valve from leader hose if
so equipped. 8. Select a proper location to mount leader hose with hose bracket provided. Avoid locations where leader hose may become tangled with wires and other hoses.
9. To mount hose bracket, drill hole with 3/16” drill bit and push self–anchoring hose bracket pin
into hole. Route leader hose through hose bracket and secure hose by pressing bracket clamp
into locked position.
10. To remove hose from the hose bracket, simply press down on the hose clamp release tab to release bracket clamp. (Fig. 3)
11. Connect compressor’s positive lead wire to one of the leads of your pressure switch. 12. Make sure that your compressor setup is properly fused. For appropriate fuse size, refer to amp
draw of compressor in the specifications section of this manual. 13. Always locate fuse as close as possible to power source. 14. Before connecting to power source, re-check to make sure that all connections are
made properly.
15. Connect and test compressor system by running the compressor for a short time to build up pressure in your air tank.
16. Once air pressure reaches preset cut out pressure of your pressure switch, the compressor will
shut off. Inspect all air line connections for leaks with soap and water solution. If a leak is
detected, the air line may not be cut squarely or pushed all the way in. (Fig. 1) 325C / 350C / 400C / 450C Compressor Installation Parts List:

OPERATING INSTRUCTIONS
1. IMPORTANT: Always operate the compressor at or below the MAXIMUM PRESSURE RATING of
the compressor. Please refer to Application & Specifications Sections of this manual for details.
2. Always observe the MAXIMUM DUTY CYCLE of the air compressor. Refer to Compressor
Applications and Specifications Sections of this manual for details. Operation exceeding
maximum pressure ratings and/or duty cycle will result in damage to the air compressor. 3. Your air compressor is equipped with an AUTOMATIC THERMAL OVERLOAD PROTECTOR. This
feature is designed to protect the air compressor from overheating and causing permanent
damage to your air compressor. The thermal overload protector will automatically cut power to
your air compressor should the internal operating temperature of the air compressor rise above
safe levels during excessive use.
4. Should at any time during use, your air compressor automatically shuts off; do not attempt to
restart it. Turn off power and allow unit to cool for about 30 minutes. This will allow the Thermal
Overload Protector to reset so you can safely resume use of the air compressor.
5. To prevent discharge of your vehicle’s battery, and enhance performance, keep the vehicle’s
engine running while using the compressor.
6. Only operate compressor in well ventilated areas.
7. The use of a relay is strongly recommended for installation of this compressor, but not included. (40-amp relay value or higher per compressor recommended).

MAINTENANCE & REPAIRS
1. Periodically check all electrical and fittings connections. Clean and tighten as needed. 2. Periodically check all mounting screws. Tighten as needed.
3. Replace Air Filter Element periodically. Replacement frequency depends on operating frequency and
operating environment. For frequent use in dusty environment, we recommend that you replace air
filter element at least once a month. 4. Regularly clean dust and dirt from compressor cooling fins and motor housing.
5. Your air compressor is equipped with a permanently lubricated, maintenance-free motor. Never try to
lubricate the compressor.
6. All repairs should be performed by Manufacturer or Manufacturer’s Authorized Service Agencies only. CAUTION:
Never touch the air compressor or fittings connected to the air compressor, with bare hands during
or immediately after use. The leader hose and fittings connected to leader hose will become very
HOT during and after use. If necessary, wear heat resistant gloves to handle fittings, air line, and
leader hose.

ABOUT COMPRESSOR DUTY CYCLE:
Duty cycle refers to the amount of time a compressor can be
operated in a given time period at 100
PSI, and a standard ambient temperature of 72° F. It is commonly expressed in percentage format:
Compressor on time ÷ (on time + off time) = Duty Cycle %.

NOTE: All compressors, regardless of rated duty cycle, require sufficient rest time in between cycles
to allow for partial or complete heat dissipation. Heat dissipation rates may vary depending on
ambient temperatures and operating conditions.
ABOUT RATED WORKING PRESSURE:
To ensure trouble free service life of your compressor, always operate compressor within rated
working pressure of the compressor. Never use a pressure switch with a higher cut-off pressure
than compressor’s rated working pressure.
